tories, incorporated, Fin a corporation oi Application November 25, 1942?, Serial No. 511512 3 Claims. (011. 173-97) My invention relates to improvements in voltage multiplying systems and has for its principal object that of providing an improved system whereby a given voltage may be multiplied or d lbled through the medium or vibrating switch or switches which are in turn driven from the same source of supply which is used to supply the load.

A further object of my invention is to provide a voltage multiplying system in which the source of electrical energy is successively connected to an energy storing means alone and then to a load circuit in series with the energy storing means.

For the purpose of disclosing my invention, I have illustrated in the accompanying drawing an embodiment thereof and in said drawing:

The figure of the drawing diagrammatically illustrates a system embodying the features of my invention.

In the system shown, I provide suitable source of power or energy which may be in the form of a battery I. This battery is connected between 2. pair of vibrating members 2 and 3 of a suitable vibrating switch. The member -2 is adapted to vibrate between the relatively stationary contacts 4 and 5 and the member 3 is adapted to vibrate between relatively stationary contacts 6 and E. An energy storage means, in the form of a capacitor 8, is connected between the con-. tacts t and 6 and .to one terminal of the load. The contact l is connected to the other terminal of the load while the contact 5 is connected to one terminal of the capacitor 8.

For driving the vibrating contact members 2 and 3, I provide a driving magnet 9, the winding of which is connected to one side of the battery l and to a relatively stationary contact l0 nor=- mally in engagement with the vibrating contact 3.

It is apparent therefore, that with the parts in their neutral position when the driving magnet 9 is energized, the vibrating contacts 2 and 3 will engage the stationary contacts 4 and 6, thus connecting the battery and capacitor 8 in series, thereby charging the capacitor. At the same time that this movement takes place on the part of the vibrating contacts, the circuit through the driving magnet will open permitting the vibrating contacts to move in the opposite direction into engagement with the contacts 5 and '1 thereby closing the circuit from the battery to the load from the load through the capacitor and then back to the opposite side of the battery, thus connecting the battery load, and condensers in series. This movement of the vibrating contacts again engage the vibrating contact reed with the relative stationary contact it, again energizing the driving magnet;

I claim as my invention:

1. In a system for multiplying the voltage delivered from a suitable source of supply and including a vibrating interrupter having a pair of vibrating contact members, the arrangement for driving said vibrating contact members from the same source of supply as that supplying the voltage to be multiplied, comprising in combination a source of supply connected between said pair of vibrating contacts, electro-magnet means for driving said vibrating interrupter and connected to said source of supply, a pair of relatively stationary contacts adapted to be respectively engaged by said vibrating contacts, a second pair of relatively stationary contacts adapted to be engaged by said vibrating contacts, and a storage capacitor connected between said first pair of contacts having one terminal connected to a load terminal and the other terminal connected to one of said second pair of contacts, the other of said second pair of contacts being connected to a second load terminal.

2. In a system for multiplying the voltage delivered from a suitable source of supply and including a vibrating interrupter having a pair of vibrating contact members, the arrangement for driving said contacts from the same source of supply as that supplying the voltage to be multiplied, and comprising in combination a source of supply connected between said pair of vibrat ing contacts, electro-magnet means for driving said vibrating interrupter connected to said source of supply, and having its circuit interrupted by said vibrating interrupter, a pair of relatively stationary contacts adapted to be respectively engaged by said vibrating contacts, a second pair of relatively stationary contacts adapted to be engaged by said vibrating contacts, and a storage capacitor connected between said first pair'of contacts having one terminal connected to a load terminal and the other terminal 7 connected to one of said second pair of contacts,

the other of said second pair of contacts being connected to a second load terminal.

3. In a system for multiplying the voltage delivered from a suitable source of supply and including a vibrating interrupter having a pair of vibrating contact members, the arrangement for driving said vibrating contacts from the same source of supply as that supplying the voltage to be multiplied. and comprising in combination a source of supply connected between said pair of vibrating contacts, electro-magnet means for driving said vibrating contacts. including a coil having one terminal connected to a relatively stationary contact and adapted to be engaged by a contact of said vibrating interrupter and the other terminal connected through said Vibrating interrupter with the other side of said source or supply, a pair of relatively stationary contacts asoaa'm adapted to be engaged by said vibrating contacts, 19

a sec d pair of contacts adapted to be engaged by s d vibrating contacts, and a storage capacitor connected between said first pair of contacts,

havingone terminal connected to a load terminal and the other terminal connected to one of said second pair of contacts, the other of said second pair of contacts being connected to a second load terminal.
